Improvement in trace-buckles



ISAAC CLARK, OF DRYDEN, MICHIGAN.

IMPROVEMENT IN TRACE-BUCKLES.

Speciioation forming part of Letters Patent No. 117,742, dated August 8,1871.

To all whom it may concern:

Be it known that I, ISAAC CLARK, of Dryden, in the county of Lapeer andState oi' Michigan, have invented a new and useful Improvement inTrace-Buckles; and I do declare that the following is a true andaccurate description thereof, reference being had to the accompanyingdrawing and to the letters of reference marked thereon, and being a'part of this specification, in which- Figure 1 is a perspective of mydevice inoperation, with section of trace attached. Fig. 2 is a likeview detached from the trace, and with the wedge-latch removed. Fig. 3is a perspective of the wedge-latch.

Like letters refer to like parts in each gure.

The nature of this invention relates to an improved construction of atrace-buckle, which is simple in opera-tion, efficient, strong, and fromwhich the trace may be easily and readilyT detached. The inventionconsists in the peculiar construction and arrangement of the variousparts, as more fully hereinafter described.

In the accompanying drawing', A represents the loop to which theholdback-strap is attached; B, the loop, to which the haine-strap isfastened; C, the loop to which the belly-band is secured; and D the loopto which the back-strap or pad is attached in the usual way. From thecross-bar I, which is secured between the sides J, rises, be-

ing rigidly affixed thereto, the stud or tongue K, which is designed toengage with the proper holes inthe tug or trace. From the sides J thererise the studs L, whose upper ends terminate in the hooks M. E is `acam-latch, provided with journals af, which are designed to engage withthe hooks M. It is also provided with a hole, F, which is designed toengage with the rigid tongue; also with a cam-shaped projection, Gr,which, when in place, rests against the trace and binds the same againstthe cross-bar H, thereby relieving lnuch of the strain upon the tongue.It will be noticed that there is a curve between the cross-bar H and thebar I, said curve being upward and rearward, and another curve betweenthe bar I and the bar N, which forms one side of a loop through whichthe trace passes, and these curves all serve as bearings to relieve thestrain upon the tongue.

What I claim as my invention, a-nd desire to secure by Letters Patent,is l The tracebuckle described and shown, consisting of the loops A, B,C, and D, rigid tongue K, hooked studs L, and cam-latch E, when theseveral parts are constructed and arranged substantially as set forth.
